Colbert then unleashed on Trump.

"Mr. President, you're not the POTUS, you're the 'gloat-us.' You're the glutton with the button. You're a regular 'Gorge Washington.' You're the 'presi-dunce,' but you're turning into a real 'prick-tator," Colbert said.'

He continued:

"Sir, you attract more skinheads than free Rogaine. You have more people marching against you than cancer. You talk like a sign-language gorilla that got hit in the head. In fact, the only thing your mouth is good for is being Vladimir Putin's c--k holster."
